    <p>I have a method called dateSelectViewController declared in my .h file as a protocol:</p> <pre><code>@class DateSelectViewController; @protocol DateSelectViewControllerDelegate - (void)dateSelectViewController:(DateSelectViewController *)sender theDate:(id)stringDate; @end </code></pre> <p>Below the protocol, I'm declaring a delegate:</p> <pre><code>@property (nonatomic, weak) id &lt;DateSelectViewControllerDelegate&gt; delegate; </code></pre> <p>and in the implementation file, I synthesize the delegate, and I send a message to the delegate when the done button is pressed in my view:</p> <pre><code>- (IBAction)DonePressed:(id)sender { NSDate *chosen = [datePicker date]; NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"MM/dd/yyyy"]; NSString *formatedDate = [formatter stringFromDate:chosen]; //sending a message to the delegate [self.delegate dateSelectViewController:self theDate:formatedDate]; [self.navigationController popViewControllerAnimated:YES]; } </code></pre> <p>In the .h file that's being delegated to, I'm importing the delegators .h file. And in the .m file I'm conforming to the protocol:</p> <pre><code>@interface MakePlantTVC ()&lt;DateSelectViewControllerDelegate&gt; - (void)dateSelectViewController:(DateSelectViewController *)sender theDate:(id)stringDate { self.displayDate.text = stringDate; NSLog(@"delegate working"); } </code></pre> <p>For some reason the this is working at all. When the done button is pressed in my delegators class, the button does as it's supposed to and pops the view controller but it's like the message is never sent to the delegate. At first I thought I could be sending a message to nil but its' of type id, so that shouldn't be the case. Why is the message not being sent? </p>

    1. COTry adding `NSLog(@"delegate = %@", self.delegate)` before sending the delegate a message.

    3. COwhile passing message to a delegate, its always nice to do a check for the availability of the delegate using this condition `if (self.delegate && [self.delegate respondsToSelector:@selector(method_name)]) { [self.delegate method_name]}`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
